Training details about different sizes about advancedeast HOT 4 OPEN

1.Does this mean to train the network in a coarse-to-fine process, which initals the network from 256x256 and then finetunes it on larger sizes?
Yes
2.Does this accelerate the converge of the network than train it on size 736x736 directly?
Yes, because direct training on size 736 is very slow

my own training method:
set cfg.train_task_id = '2T256'
set patience 5(between 2~6)
python preprocess.py && python label.py && python advanced_east.py

when end of training, copy the best saved weights file(.h5) to initials the training of size 384, modify cfg.train_task_id = '2T384' and cfg.initial_epoch="the ending epoch" and cfg.load_weights=True and continue train.

then train 512 and so on. You could try this method, maybe there are better ways.

@huoyijie whether the network still remembers what they learned in 256 while training 736?

Hi,
I download tianchi ICPR dataset,set cfg.train_task_id = '3T256',run python3 preprocess.py && python3 label.py && python3 advanced_east.py. But I get this error. The output information is shown below. How can I fix this error? Can you help me?@LucyLu-LX @huoyijie @hcnhatnam

@globalmaster it isn't error. The training is stopped early(early stopping) to avoid overfit. Looks like the model is not converging and this is still my problem. @globalmaster, Can you share for me dataset with google driver link?
